Analysis of urine is a widely used diagnostic tool that traditionally measured one or, at most,
a few metabolites. However, the recognition of the need for a holistic approach to …

This paper reviews the prevalence of legal and illegal stimulants in relation to doping-control
analysis. Stimulants are among the oldest classes of doping agents, having been used since …

This work presents a new material, ie, a porous graphene ink to modify on the GCE surface
(P Gr-ink/GCE) to improve sensitivity by increasing the surface area of the electrode for the …

One of the greatest challenges in anti‐doping science is the large number of substances
available and the difficulty in finding the best analytical targets to detect their misuse …

Zebrafish (Danio rerio) water tank (ZWT) approach was investigated as an alternative model
for metabolism studies based on six different experiments with four model compounds …

Purpose This study aims to investigate a zebrafish (Danio Rerio) water tank (ZWT) as an
alternative model for the study of the metabolism of xylazine. Methods The ZWT approach for …

Sibutramine hydrochloride (SH) is a banned weight-loss drug, but its illegal addition to
health products is still rampant. This suggests a very urgent need for a fast and precise …

This article presents the prevalence of stimulant doping among Brazilian athletes, the
analytical approaches used, as well as a general evolution of the detectability of the …

Sibutramine is a monoamine re-uptake inhibitor used for the treatment of obesity. In the
present study a rapid, sensitive and economical HPLC method was developed and fully …

A novel graphene-modified molecularly imprinted polymer-based electrochemical sensor
(MIP/RGO-GCE) was developed for the sensitive and selective detection of sibutramine in …
